are there major discrepancies by the time the season is over between the rankings of teams by PP "opportunities" and by "actual PP time"? My assumption has always been that the official and well-known PPO stat is a very reasonable proxy for PP time. let's see:

therefore, I am still comfortable using PPO as a shorthand without worrying about actual PP time.

how are major penalties tabulated in official stats?
I've heard some people say that a 5 minute PP is tallied as 1 PP, I've also heard it's tallied as 1 more PP than goals scored during it.

So if a team gets one powerplay in a game-a 5 minute major and scores 3 goals on it, what would their powerplay stats be for the game? 3 for 1 or 3 for 4?

Every time a goal is scored, a new PP opportunity is deemed to have begun. So if a team scores 3 PPGs on a major they would be deemed to have 4 opportunities. Also, if the team on the PP takes a two minute minor, making it four-on-four, the team is credited with another PPO when their penalized player is back on the ice.

Vancouver was credited with 11 power play opportunities for the game:
- 7 minor penalties taken by the Bruins
- 4 opportunities for the five minute major:
a) one opportunity for the first minute until Henrik's goal
b) one opportunity for the time between Henrik and Hodgson's goals
c) one opportunity for the time between Hodgson's goal and Daniel's penalty
d) one opportunity for the 16 seconds of power play time the Canucks had after Daniel finished serving his penalty

Pre 1956-57 complete two minute minors had to be served regardless of the number of goals scored against the penalized team.

No official PP stats were kept but in media reports teams would be described as scoring multiple goals during 1 PP.

Do the same procedures apply to defining SH goals and opportunities? It is possible for a penalized team to score multiple SH goals in two minutes. A SH goal also splits the PP opportunity into two segments.

No because it's the same as any other powerplay with a stoppage in play not changing the manpower advantage.

Now assume the following scenario;
Team A minor penalty @ 3:00
Team B minor penalty @ 3:30
Team A minor penalty @ 3:45

Let's assume no goals are scored; team B would be on the PP from 3:00-3:30, then again from 3:45-5:00 (4 on 3) and then again from 5:30-5:45. Would they be charged with 3 powerplays?

Apologies for the resurrection. But I always found the "goals/PPO" metric to be flawed in measuring how efficient a PP is. There are numerous times where a PP is cut short by the PP team taking a penalty and negating the whole thing, but it still counts as a PPO. Wouldn't a more accurate measure be "time on PP/goals"?
